Title: Connector for circuit board
Inventor: SAITO MASAJI
IPC: H05K3/30
Filed: 1996-04-16
Abstract: PROBLEM TO BE SOLVED: To prevent any increase in stress in a soldered portion between a terminal pin and a circuit board at the time of thermal expansion. SOLUTION: A through hole 33 formed on an alignment plate 30 is constituted of a holding portion 33A, into which a terminal pin 20 is fitted, and a releasing portion 33B larger than the holding portion 33A. When the terminal pins 20 are fitted into a circuit board, the terminal pins 20 are aligned by the holding portions 33A. After fitting, the alignment plate 30 is moved, so that the terminal pins 20 are positioned inside the releasing portions 33B. Even if the through hole 33 is deviated with respect to the terminal pin 20 at the time of thermal expansion, the terminal pin 20 cannot be pressed by the edge of the through hole 33, thereby preventing any increase in stress in a soldered portion.

Title: Optical switch
Inventor: NISHI NORIO
IPC: G02B6/35
Filed: 1980-07-14
Abstract: PURPOSE:To obtain a miniaturized and simply constructed optical switch by adhering a ferromagnetic thin film to the peripheral surface of each one end of input and output optical fibers so that they are opposed to each other and attaching a driving coil for the generation of magnetic field to the surroundings of the movable coil of input optical fiber.

These films are magnetized so that different magnetic poles are generated on the surroundings of ends 5, 6 and 7. When current is fed to a coil 10 to generate a vertical magnetic field, the input fiber 1 and output fiber 2 are matched by the magnetic absorbing force. If reversed current flows into a coil 10, the input fiber 1 and the output fiber 2 are matched. Thus, the miniaturized and simply constructed optical switch can be obtained.

Title: Pressure reducing valve and hot water supply facility
Inventor: KONDO SEI
IPC: F24H1/18
Filed: 1995-04-20
Abstract: PURPOSE: To decrease the component cost and prevent hot water of high temperature from spouting out owing to a return flow of hot water when a water plug is operated so as to spout only water by using the pressure reducing valve which is provided with plural outflow ports on a more downflow side than a pressure reducing operation part. CONSTITUTION: The pressure reducing valve 10A is provided with the outflow ports 40 on a more downstream side than the pressure reducing operation part. A nipple 90 is screwed in an opening 42 and a secondary water feed pipe to omit a three-way joint. Namely, the component cost is reducible since no three- way joint is necessary, and in this hot water supply facilities, the return flow of hot water enters the pressure reducing valve 10A through an elbow joint and then enters the secondary water feed pipe, so the return flow of hot water reaches the secondary water feed pipe through a longer path than before, so that the amount of the return flow of hot water which reaches the secondary water feed pipe actually is reduced.  Further, the heat capacity of the pressure reducing valve 10A is large and the inside of the pressure reducing valve 10A is in a complicated shape, so the return flow of hot water entering the pressure reducing valve 10A has heat absorbed by the valve body 12 and is cooled.

IPC: H04N5/937
Filed: 1988-04-18
Abstract: PURPOSE:To avoid waste of preparation of separate master tapes corresponding to the transmission rate by using a common master tape even if any of plural transmission rates is selected. CONSTITUTION:When the result of confirmation of content of a color still picture by a monitor TV 20 is enabled for recording, a digital video signal from a hard disk 17 read under the control of a minicomputer 15 is fed to a PCM processor 22, a horizontal and a vertical synchronizing signal are added to be a pseudo composite video signal and the result is fed to a VTR 23 and recorded on a master tape 24. Then the same master tape 24 is used in common independently of the difference of the transmission rate of the picture signal and the common software is recorded and reproduced on the recording medium with a different transmission rate. Thus, a trouble of preparing separate master tapes depending on the transmission rate of the recording medium is saved.

Filed: 1993-03-29
Abstract: PURPOSE:To activate the surface of an electrode and improve the discharge characteristic by storing hydrogen in a molding, polarizing it to the prescribed oxidation-reduction potential, and charging/discharging it in an alkali hydroxide aqueous solution. CONSTITUTION:A hydrogen storage alloy is crushed, and alloy powder is coated with porous copper by electroless plating. The powder and a polytetrafluoroethylene dispersion liquid are kneaded and formed into a sheet shape to prepare a molding for an electrode. The molding is put into an alkali hydroxide aqueous solution containing no oxidant, and hydrogen is electrochemically stored. It is then polarized to the potential lower than the Ni/Ni(OH)2 oxidation-reduction potential in the alkali hydroxide aqueous solution containing an oxidant having a nobler oxidation area than that of a standard hydrogen electrode. The molding is charged/discharged in the alkali hydroxide aqueous solution containing no oxidant. The hydrogen stored in the electrode and the metal other than nickel existing on the surface of the electrode can be oxidized. A layer constituted of metal nickel and another metal oxide is formed on the surface of the electrode, and the radiation characteristic can be improved.
